I recently noticed that evolution performance put the OEM 2012 Boss 302 intake manifold on there site as a pre-order for sale item.
This of course spurred my interest as it looks like a much different design than the stock '11 IM, not just a change made for appearance or a slight tweaking of the previous design.
According to ford, this is a "Runner in the box" manifold, which means nothing to me. Ive never heard that terminology used before.
If anybody can enlighten me on what exactly that means I would be delighted.
But anyway...
After searching some more I found this article:
2012 Ford Mustang Boss 302 First Look
In which it says:
Sounds interesting, eh?
The other adaptations to the engine (such as sodium filled valves and forged pistons) sound like they are not really upgrading output, but simply making it capable of sustaining the high rpm abuse of the raised rev limit (7500 rpm).
So it makes sense that the real power improvement is coming from this IM and the new cam profile (which apparently has zero peak increase in lift, so we can only assume its got a little more duration somewhere, it cant be that much more radical).
It may be safe to assume that this may provide an extra 20-30 hp to the '11 GTs that already have bolt-ons and provisions for tuning. I personally cant wait to see what happens.

The more obvious change from the outside is the adoption of a new short-runner composite intake manifold sitting in the valley between the cylinder heads.
"The effect of the new intake design is dramatic," said Mike Harrison, Ford V8 program manager in a release. "When I took the prototype car to Mustang chief engineer Dave Pericak, he took a short drive, tossed me the keys and said 'Book it...it's in the program.' He knew what we were onto, and that's really the point where the Boss 302 was born."
